FLOAT-VALVE FOR. WATER CLOSETS.

SPECIFICATION forming part of Letters Patent No. 317,710, dated May 12, 1885.

(No model.)

To aZZ whom it may concern:

Be it known that I, AUGUST F. BLESCH, of Columbus, in the county of Franklin and State of Ohio, have invented a new Improved Float-Valve for Water-Closets, of a which the following is a full, clear, and exact description.

The object of my invention is to provide for the easy, positive, and noiseless closing of the float-valve controlling the supply of water for flushing water-closet basins or bowls.

The invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a plan view of the valve-case and pipe-connections thereto, and the float, with parts broken away; and Fig. 2 is a vertical sectional elevation on the line 00 m, Fig. 1.

The letter A indicates the valve-case, which I show made in two parts or sections, a a, connected by bolts or screws b, and with a leather packing, B, at the joint, which packing serves as the seat on which closes the brass valve 0, which is fixed on the stem D, held in the valve-case.

A cup-leather, E, held on the stem D, works in the part c of the valve-case and prevents leakage of water around the stem at the head of the case.

A cup-leather, F, is held to the stem D at its lower end, and so as to fit and work in a cylinder, Gr, formed for it in the part a of the valve-case, which cylinder is of the same diameter as the valve 0, and has a small hole, 9, through which water which may chance to pass the cupleather F may escape to the floatchamber of the water-closet.

H is the float, which rises and falls in the water-chamber made for it at the side of the bowl or basin of the'closet, and connects by a lever, I, with the valve-stem D at d, and is fulcrumed at iback of the stem, so that as the float falls the valve 0 will be opened downward, and as the float rises the valve 0 will be closed.

J is the water-inlet pipe, which may lead from any source of supply, so as to allow the water to pass the open valve 0, and thence through the outlet-pipe K, which leads to the flushing-pipe rim or chamber of the closetbowl to flush the bowl after use of the closet.

In the operation of my improved float-valve it will be seen that the downward pressure of the water on the piston F at all times equals the upward pressure on the valve 0, balancing the same under all circumstances, and as the main valve of the closet-bowl is opened and the water in the communicating floatchamber passes oh, the float will fall, which movement opens the valve 0, to admit the water from the pipe J to the pipe K for flushing the bowl, and that while the valve 0 is closing by the rise of the water in the floatchamber lifting the float the pressure of the water will press downward on the cup-leather or piston F, thereby allowing the float to lift the valve to its seat easily, positively, and noiselessly, or without the thumping or water-hammer common to many valve constructions.

Instead of using the cup-leather E, the stem D may be packed in any suitable manner.

Any suitably-packed disk or piston may be used in place of the cup-leather F.

This valve can be used for other purposesas, for instance, as a ball-valve for watertanks.

I am aware that a valve-stem has been extended below the valve and provided with a piston working in a chamber having its sides recessed for the admission of water to the same,-and I therefore do not claim such invention.

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent-- In a float-valve, the combination, with the valve-stem D, provided with the valve 0 and the piston F, the float H, and means for con- 9 5 necting the float to the valve-stem, of the casing A, provided with the inlet and outlet openingsJ K, and the chamber G, arranged directly below the valve-seat and provided with an exterior opening in its lower part, to prevent the accumulation of water therein, thesaid chamber being" outside of the inlet J 5 and the communication between the two be-v ing practically closed by the piston when the latter is in position, substantially as herein shown and described, whereby provision is made for perfectly balancing the valve and utilizing the pressure of the water for assist- 1o ing the float to press the Valve-stem downward, as set forth.

, AUGUST F. BLESGH.
